PAPER FASTENER.

Application filed August 28, 1925. Serial No 53,014.

ToaZZ whom. it may concern: I

Be it known that 1, CHARLES D. KING, a citizen of the United States, residing at Rutherford, in the county of Bergen and 8 State of New Jersey, have invented certain new and useful Improvements in Paper Fasteners, of which the following is a specification,

This invention relates to paper fasteners for use in holding flat files of papers, letters, documents, manuscripts, and the like, and particularly to paper fasteners embodying tongues to be pushed through the papers to be held and the projecting portions then bent down on the same, and of the type disclosed in my copending application Ser. No. 715,274 May 23, 1924. The main objectof the invention is to provide improved means for covering the bent down portions of the tongues and preventing them from catching on adjacent objects such as loose papers, files and other things, and for preventing loose papers being cau ht and held or torn by them, particularly after such tongues have by continued use become bent and crooked so as to project sufficiently above the papers when the tongues are bent down on them.

The means I prefer to employ for accomplishing these objects together with other advantageous features of my improved paper fastener, are illustrated in the drawing accompanying and forming part of this specification, and in which Figure 1 is a plan of one form of my improved paper fastener applied. to a file of papers.

Like characters of reference refer to like parts in all the figures of the drawing.

Referring to the drawing, the numeral 2 denotes a member provided with tongues such as 3, spaced apart and adapted to be bent up at right angles to the middle por tion and then pushed through a file of papers such as 5, whereupon the projecting portions of the tongues and the ends thereof can be bent down on the topmost paper, thus holding and binding the papers togetherf There is also a member 8, one form of which is shown alone in Figs. 3 and 5, which member is adapted to be placed over and cover the bent down portions of the tongues 3. The member 8 is provided with an underneath groove, channel or recess 9, preferably of the proper width and depth to allow the said bent down portions of the tongues to lie snugly therein. Near each end of the member 8 and adjacent to the bends of the tongues 3, are devices whereby the member 8 can be attached to the bent down portions of said tongues 3.

The said devices include members 15 preferably in the form of depending lateral tongues oppositely disposed near the ends of the covering member 8 respectively and adapted to be pushed under the bent down In the form shown in Fig. 1 there are also other members 16 which are in fact extremely short tongues that can be slipped under the edges of the bent down tongues 3 near the tongues 15 but on the opposite side so that there is a member 16 diagonally opposite to each of the members '15.

In the form shown in Figs. 3 to 7 inclusive the members 16 do not appear and in this form it is advantageous to form the groove or channel 9 with very little clearance so that the member 8 tends to be centered by the groove. 1n the first form however the clearance may be considerably more and also in the form shown in Figs. 10 to 12 inclusive. In Figs. 10'to 12 there is a lip or downward projection 17 opposite the point or free end of the lateral tongue 15 which tends to hold the member 8 in tongues 15 cm be pushed between'a bent down' tongue and the paper'near the bend of the tongue. The otherend of the mem her 8 is then moved laterally so as to push the other tongue 15 under the other bent down tongue near its bond. The lateral tongues ilSniay be arrai'iged each with an incline downward"towardthe point to facilitate their application underthe bent down tongues. \Yhen the member is pushed laterally over the said bentdown tongues, it is finally centered over them in some forms by a final snap action as the groove 9 suddenly slips' into position on said tongue portions. In other-forum the'placing central is effected by observation on thepart of the operator.

The above described'mode of attaching the members 8 is very advantageous for the reason that the members '8 are held against the papers in a more balanced manner and sothat all parts of the edges 11 thereof are in good contact with the topmost paper. If desired the member 8 may be slanted toward the edges to improve the contact when the member is-applied to papers.

The device is particularly advantageous for use when the bent down portions of the tongues have been much used and are full of crooks and kinks and which condition is very objectionable with many tongue shields now in use. Vith my member 8' crooks and bends in the-tongue portions tend to assist in keeping the member 8 more firmly in place as they tend to increase the holding pressure ofthemembers 8 when placed over the bent down tongues with "the lateral tongues 15 under such bent down portions.

Wh at I claim is l. A paper fastener embodying spaced apart tongues to be pushed through papers and the projecting-portions bent down on the same, a member to be placed over and cover said bent down tongue portions, and means to secure said covering member to said bent down tongue portions which include two elements to be moved under them in relatively op osi-te directions.

2. A paper astener embodying spaced apart tongues to be pushed through papers and the projectin port-ions bent down lengthwise of the fastener on said papers, :1. member to be placed over and cover said bent down tongue portions, and means to secure *said member to said bent down tongue portions which include two oppositely disposed elements which are movable into position under said portions in relatively opposite directions.

3. A paper fastener embodying spaced apart tongues to be pushed through papers and the projecting portions bent down on the same, a member to be placed over and cover said bent down tongue portions, and means to'secure said covering member to said portions which include a plurality of elements to be moved under them, part of which elements are movable laterally under them in one direction and the other part of which elements are movable under them in the opposite direction.

i; A (paper fastener "en'ibodying spaced apart tongues to be pushed through papers and the projecting portions bent down on the same lengthwise of the fastener, a member to be placed over and cover said bent down tongue portions and having a longitud'inal groove in its under side in which groove the bent down tongue portions can lie, and nieanstosecure said covering member to the bent down tongue portions which include two elements to be moved under them'laterally from opposite sides and in relatively opposite directions.

5. A paper fastener embodying two spaced apart tongues to be pushed through papers and the projecting portions bent down on the same, amember to be placed over and cover said bentdown tongue portions and having an underneath groove in 'which the said bent down tongue portions can lie, and means tosecure said member to said bent down ton 'ue portions which includetwo laterally isposed portions movable under them in relatively opposite 'directions and adjacent to the bends of said bent down tongue portions.

6. A paper fastener embodying two spaced-apart tongues to be pushed through papers and the "projecting portions bent down on the-:sam'aa member to be placed over and cover said bent down tongue-p01 tions and having an underneath groove in wli-ich said bent down tongue portions can lie, and means'to secure said covering memher to said bent down tongue portions which include two lateral, depending tongues on said member andwhich by movi'ng said member are adapted to be pushed laterallyunder said bent down tongue portions in relatively opposite directions, and

mea ns cooperating with said lateral tongues whereby the covering member can be centered-over the bent down tongue portions.

7. A paper fastener embodying two spaced apart-tonguesto be pushed through papers'and the projecting portions bent down on the same, a member to beplaced over and cover said bent down tongue portions and having an underneath groove in which said bent tongue portions can lie, and means to secure said covering member to said bent down tongue portions which include two lateral, oppositely disposed, depending tongues on said member on opposite ends thereof which by moving said member laterally are adapted to be pushed 1 under said bent down tongue portions in relatively opposite directions and two oppositely disposed cooperating portions whereby the covering member can be secured in position over said bent down tongue portions.
